RP-A501 is being developed for Danon Disease, a rare genetic disorder characterized by thickening and weakening of the heart muscle, often resulting in heart failure, and for male patients, frequent death during adolescence or early adulthood. Rocket is the first company demonstrating safety and efficacy data in clinical studies for gene therapy targeting the heart.

An open-label, global Phase 2 pivotal clinical trial of RP-A501 for the treatment of Danon Disease has commenced. The trial is expected to enroll 12 male patients from the U.S. and EU. The trial will assess a co-primary endpoint consisting of LAMP2 protein expression and left ventricular (LV) mass reduction from baseline at 12 months.

Frequently Asked Questions

The Natural History of a Disease is the typical progression of the disease over a person’s lifetime starting from its onset

Natural History studies are observational studies that gather comprehensive data on the course of the disease to gain a better understanding of its progression and impact on patients. Data captured may include information on the physical signs and symptoms patients experience, test results (for example blood tests or imaging), genetic information, and health-related quality of life, over a period of time. This information helps describe the disease course and identify important factors (e.g. demographic, genetic, and/or lab test results), that may contribute to better or worse disease outcomes.

Travel, accommodation, and food stipend would be provided. Study assessments are provided free of charge.

Natural History Studies are particularly important for rare diseases. Given the diversity of symptoms and the small size of the patient population, these studies are often the only opportunity for researchers and physicians to address significant knowledge gaps and obtain a robust understanding of the disease and patient experience.

Engaging in a Natural History Study offers numerous benefits to the community, such as:

  • Raising awareness in medical, academic and pharmaceutical sectors
  • Empowering rare disease patient communities with knowledge and support for advocating better healthcare policies and support services
  • Enhancing patient care with improved insights into disease progression, allowing for more personalized treatment plans and potentially earlier detection of complications
  • Contributing to advancements in healthcare

These studies provide various avenues to help inform and design clinical trials, such as:

  • Highlighting areas of unmet medical need
  • Understanding characteristics of the patient population to define a treatment benefit from a patient’s perspective.
  • Describing disease progression, enabling the identification of clinical outcome measures and biomarkers
  • Provide patient-centric data for health authorities such as the FDA, and other public health institutions to use in their review processes of investigational treatments.

Danon Disease Resources

Danon disease is a rare genetic disorder that is characterized by severe and primarily hypertrophic cardiomyopathy. Skeletal muscle weakness and mild cognitive impairment are also common. The causative mutation has been identified in the gene encoding for lysosome-associated membrane protein (LAMP2), and in particular the LAMP2B version of the gene. Affected cells cannot efficiently digest and recycle protein and other materials, leading to dysfunction.

RP-A501 is an investigational gene therapy consisting of a recombinant adeno-associated serotype 9 (AAV9) capsid containing a functional version of the human LAMP2B transgene which is administered as a single intravenous (IV) infusion along with a medication regimen to manage immune response. RP-A501 has the potential to restore or stabilize cardiac function in patients with Danon disease.
